Night of the Lepus (1972) Spoiler-Free Summary – What It's About

In a sun‑scorched stretch of Arizona where the horizon seems to stretch forever, an unexpected ecological emergency has taken root. A sudden boom in rabbit numbers—now grotesquely larger and far more aggressive than any ordinary herd—has begun to threaten crops, water sources, and the fragile balance of rural life. The film opens with a tone that blends stark western grit with uneasy scientific dread, letting the desolate landscape itself feel like a character that both shelters and suffocates its inhabitants.

Cole Hillman, a hardened rancher who lives by the rhythm of his land and the health of his cattle, is forced to confront a problem that his familiar tools can’t solve. He watches his livelihood teeter on the edge of ruin, aware that conventional weapons or poison could do more harm than good. Seeking a viable answer, he turns to Dr. Elgin Clark, an earnest university researcher whose expertise lies in understanding the very wildlife that now overwhelms the valley. Their uneasy partnership highlights a clash of pragmatism and idealism, where each man must grapple with the consequences of intervening in nature’s course.

Enter the Bennett family—Roy, his partner Gerry, and their bright‑spirited daughter Amanda—who operate a modest lab devoted to humane, environmentally sound pest control. Their work, which ranges from bio‑engineering to inventive animal behavior studies, offers a glimmer of hope amid the growing crisis. As the rancher and the scientists exchange ideas, a subtle tension builds between the rugged, no‑nonsense world of the open range and the cautious, experimental realm of academia. Together they hint at a larger question: how far will people go when the balance of nature tips into chaos, and what unexpected alliances might form when survival hangs in the balance?
